He had a 17-year medical history of hypophysoma and diabetes insipidus. Physical examination revealed an infiltrated plaque with central ulceration in the left groin. Histopathological examination showed diffuse infiltration of lymphocytes,eosinophilic granulocytes,and histiocytoid cells in the superficial dermis. The proliferative histiocytoid cells showed mild atypia,partly with kidney-shaped nuclei. Immunohistochemical examination showed that histiocytoid cells were positive for CD1a,S-100 and CD68,and weakly positive for Ki-67（〈5%＋）. The diagnosis was adult Langerhans cell histiocytosis.
